Brad Davidson 31a6386994 Improve egress selector handling on agentless servers
Don't set up the agent tunnel authorizer on agentless servers, and warn when agentless servers won't have a way to reach in-cluster endpoints.

Brad Davidson b550e1183a Remove control-plane egress context and fix agent mode.
The control-plane context handles requests outside the cluster and
should not be sent to the proxy.

In agent mode, we don't watch pods and just direct-dial any request for
a non-node address, which is the original behavior.

Increase agent's apiserver ready timeout (#4454)
Since we now start the server's agent sooner and in the background, we
may need to wait longer than 30 seconds for the apiserver to become
ready on downstream projects such as RKE2.

Since this essentially just serves as an analogue for the server's
apiReady channel, there's little danger in setting it to something
relatively high.

Initial Logging Output Update (#2246)
This attempts to update logging statements to make them consistent
through out the code base. It also adds additional context to messages
where possible, simplifies messages, and updates level where necessary.

Darren Shepherd 2f5ee914f9 Add supervisor port
In k3s today the kubernetes API and the /v1-k3s API are combined into
one http server.  In rke2 we are running unmodified, non-embedded Kubernetes
and as such it is preferred to run k8s and the /v1-k3s API on different
ports.  The /v1-k3s API port is called the SupervisorPort in the code.

To support this separation of ports a new shim was added on the client in
then pkg/agent/proxy package that will launch two load balancers instead
of just one load balancer.  One load balancer for 6443 and the other
for 9345 (which is the supervisor port).
